MEANS FOR CONTROLLING THE QUANTITY AND QUALITY OF THE PRODUCTION OF GAS.

Application filed October 12, 1909. Serial No. 522,326.

To all whom it may concern.

Be it known that 1, JOHN M. RUsBY, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Means for Controlling the Quantity and Quality of the Production of Gas, of which the following is a specification.

One object of the present invention is to provide simple and easily applied means by which the quantity and quality of the production of gas may be controlled.

Another object is to effectan economy in the use of power for creating the air blast, and other objects will appear from the following description.

To these and other ends hereinafter set forth the invention stated in general terms comprises, first, the combination with the gas generating apparatus and its fluid supply connection of automatic means for maintaining a constant flow per unit of time past a given point in the connection; second, the combination of the gas generating apparatus, an air connection thereto including blast or draft creating means, and means operatively attached to said connection and responsive to the volume of air per unit of time passing through the connection and adapted to throttle the power applied to the blast or draft creating means; and third, the improvements hereinafter described and claimed.

In the drawings, Figure 1, is an elevational view of apparatus embodying features of the invention. Fig. 2, is a top or plan view of parts of the same and Figs. 3, 4, and 5, are views partly in elevation and partly in'section of parts that may be used interchangeably in the apparatus of Figs. 1 and 2.

The gas generating apparatus chosen for explanation comprises the generator 1, the carbureter 2 and super-heater 3 and is especially adapted to make water gas, but the invention is applicable in whole or in part to apparatus for making other kinds of gas. In the use of this apparatus air and possibly some gas, is blown through it for a certain interval so as to heat it up and this is called the blow and steam is blown through it for a certain interval so as to generate gas, and this is called the run and these opera- Patent -d Dec. 28,1915.

tions are repeated; thus in the gas making operations different fluids are alternately introduced into the apparatus. The introduction of the appropriate quantity of these fluids is important, for example, if too much or too little steam is introduced there is waste of heat, undue heating or cooling of the fire and injury to the quality of the gas, not to speak of other troubles, and in the case of air, it is important to introduce the right quantity regardless of fire and other conditions in the apparatus, so that during successive runs the apparatus will be in any desired condition of heat.

4, is an air pipe with branches 5, 6, and 7, that lead respectively to the generator, carbureter and super-heater.

8, is a blower for supplying air to the air pipe 4, and 9 is a prime mover for driving the blower. These are one example of steam actuated means but are not the only examples of well known means for creating a blast or draft and are chosen merely for the sake of explanation and description.

Operatively arranged in respect to the air pipe or air connection are means adapted to respond to the volume of air per unit of time passing through the connection and adapted to throttle the prime mover. These means may assume various forms. As shown in Figs. 1 and 2. they comprise an ajutage 10. and as shown in Fig. 3 they comprise a perforated diaphragm 11. and as shown in Fig. 5, they comprise a Pitot-tube 12, and as shown in Fig. 4, they comprise a movable disk or vane 1.3.

In Fig. 1, the pipe connections 14: and 15 of the adjutage are connected with the float device 16. This is true of the pipe connections 17 and 18 which communicate with the air connection 4 on opposite sides of the diaphragm 11, Fig. 3, and it is alsotrue of the pipe connections 19 and 20 of the Pitot-tube, shown in Fig. 5. In Fig. 1, the vane or disk 13 is connected with one end of a rod 21 pivotally mounted through the wall of the pipe connection 1 and having its other end connected with a tension spring 2 In the devices of Figs. 1, 3 and 5. the rod 23 of the float device 16 is connected with the throttle of the prime mover 9. As shown in Fig. 4, the rod 21 is connected as by means of a link 21 with the throttle valve of the prime mover.

In connection with the branches that lead to the carburetor and super-heater, may be employed devices similar to those above described. In Figs. 1 and 2, they are shown to be the same as the device connected with the branch pipe that leads to the generator and the corresponding parts of them are marked with the same numbers having the exponent a. The rods 23 of these devices operate upon dampers 25, arranged in the branches 6 and 7. These devices last described operate to control, automatically, the volume of air introduced into the carbureter and super-heater and the device 10 and its connections in the branch that leads to the generator operate upon the throttle so that energy is not wasted in supplying more air pressure than is required to meet the needs of the apparatus.

A 'Pitot-tube is possessed of advantages for the Work in hand. It is comparatively simple in construction and easy of application.

The part 1, is a generator and also a gas producer in the sense that air is blown through fuel contained in it so as to make producer gas. The branch 5, is 'a means for supplying primary air to the producer so as to make the producer gas. The branches 6 and 7, are each means for supplying secondary air to the apparatus, the secondary air serving to burn the producer gas in the chambers 2 and 3, so as to heat them. The ajutages l0 and 10, with their described connections are means for automatically regulating the flow of such primary and secondary air so as to maintain a flow of a constant volume or air per unit of time past a given point in their respective pipes, branches or ducts.

What I claim is:

1. Means for controlling thequantity and quality of the production of gas which comprises the combination of a gas generating apparatus, an air connection thereto including a means for creating a blast or draft, and means operatively attached to said connection and responsive to the volume of air per unit of time passing through the connection and adapted to throttle the power applied to said draft or blast creating means, substantially as described.

2. In apparatus for use in the manufacture of gas, the combination of agas producer; means for supplying the primary air to the producer; means for supplying the secondary air to the apparatus; and means for automatically regulating the flow of such secondary air so as to maintain a flow of a constant volume per unit of time past a given point in the secondary air duct.

3. In apparatus for use in the manufacture of gas, the combination of a gas producer; means for supplying the primary air to the latter; means for supplying the secondary air to the apparatus; and means for automatically regulating the flow of such primary and secondary air, so as to maintain a flow of a constant volume of air per unit of time past a given point in their respective ducts.

4. In apparatus of the class described, the combination of the gas generating apparatus; means for supplying air; a duct connecting the latter and said generating apparatus and means for automatically maintaining a flow of a constant volume of air per unit of time past a given point in said duct.

5. In apparatus of the class described, the combination of a gas producer; means for supplying air to the latter; and means in connection with said air supplyingmeans for automatically and continuously maintaining a flow of a constant volume of air per unit of time past a given point in said producer, independently of the area of opening of the latter.

In testimony whereof I have hereunto signed my name.

JOHN M. R UsBY.
